Iterations

on 09 Oct 2019  Posted by Administrator  Category: Security News  

When using MicroSD cards as hard drives, one simply has to swap out the SDcard, to get another iteration of the operating system and software for testing against original and future configurations. 

Think of it as a method rapid parallel prototyping, without buying multiple copies of the hardware.

In this case we are using Single or Multiple Raspberry Pi 4B's for speed testing of advanced functions like decryption or bruteforce hash cracking.    Instead of buying multiple sets of the hardware all we did is get extra MicroSDcard.   We work on one set of dev and testing, then switch SDcards and try a slightly different iteration.  

The "Skunk" - a mail-able computer that calls home from "on the road."

on 01 Oct 2019  Posted by Administrator  Category: Security News  

Today we invented a new "Mail-able" Computer that tracks itself as its being transported, measures radio channels, temperature, pressure, motion, speed and "calls home" when it finds an open network.

We named it "The Skunk" because it is small and mostly black with a little antenna "tail," all inside a sealed shipping envelope. 

Sorry, it is proprietary technology and not for sale at this time, but maybe soon.  - Todd
